Abstract

A passenger seat comprising: a frame element, vehicle anchorage means connected to the frame element, a seat body comprising a resilient material fixed with respect to the frame element and trim cover attachment means, the trim cover attachment means comprising a relatively high density, rigid foam member having a groove disposed in a surface thereof, the groove capable of receiving connection means comprised in a trim cover. A process, system and mold for producing a passenger seat are also described.

Claims

1. A mold for production of a passenger seat comprising a frame element constructed of a relatively high density, rigid foam and comprising trim cover attachment means, the mold comprising a first mold half and a second mold half engageable to define a mold cavity, the first mold half adapted to carry the frame element in a manner such that trim cover attachment means embedded in the frame element is adjacent to an interior surface of the first mold half, the first mold half further comprising sealing means disposed on the interior surface thereof at a location relatively peripheral to a position corresponding to the trim cover attachment means embedded in the frame element, said sealing means providing a seal to prevent an ingress of foam into said trim cover attachment means.

2. The mold defined in claim 1, wherein the sealing means is a dam.

3. The mold defined in claim 2, wherein the dam has a height of less than about 10 mm.

4. The mold defined in claim 2, wherein the dam has a height in the range of from about 2 mm to about 8 mm.

5. The mold defined in claim 2, wherein the dam has a height in the range of from about 2 mm to about 6 mm.

6. The mold defined in claim 2, wherein the dam has a height in the range of from about 2 mm to about 4 mm.

7. The mold defined in claim 2, wherein the dam is disposed along substantially an entire periphery of the interior surface of the first mold.

8. The mold defined in claim 1, comprising pressing means for pressing the frame element against the first mold half.

9. The mold defined in claim 8, wherein the pressing means comprises a member disposed on an interior surface of the second mold half and projecting into the mold cavity.

10. The mold defined in claim 8, wherein the pressing means comprises a plurality of members disposed on an interior surface of the second mold half and projecting into the mold cavity, the members operable to press the frame element against the interior surface of the first mold half upon engagement of the first mold half and the second mold half in a closed position.

11. The mold defined in claim 1, further comprising receptacle means for receiving vehicle anchorage means embedded in the frame element.

12. The mold defined in claim 11, wherein the receptacle means comprises an aperture which permits the vehicle anchorage means to extend to an exterior of the first mold half.

13. The mold defined in claim 12, further comprising pulling means for pulling vehicle anchorage means extending through the aperture to press the frame element against the interior surface of the first mold half.

14. The mold defined in claim 13, wherein the pulling means comprises a hydraulic cylinder.

15. The mold defined in claim 13, wherein the pulling means comprises a pneumatic cylinder.

16. The mold defined in claim 1, further comprising vent means located in a part-line between the first mold half and the second mold half.

17. Apparatus for producing a foamed automobile passenger seat, comprising:

a first mold for producing a substantially rigid foam frame element, said first mold having a first mold half and a second mold half which together define a mold cavity, the first mold half adapted for forming at least one groove along a periphery of the rigid foam frame element, and

a second mold, having the shape of an automobile seat, for adhering the rigid foam frame element to a resilient foam, the second mold comprising a third mold half and a fourth mold half which together define a seat mold cavity, the third mold adapted to support the frame element to cause automobile seat trim cover attachment means to be adjacent to an interior surface of the third mold half, the third mold half having a ridge disposed at a peripheral portion thereof corresponding to the trim cover attachment means in the frame element, said ridge providing a seal against ingress of liquid foamable polymeric composition into said automobile seat trim cover attachment means.
